IMPROVEMENT IN CARRIAGE KING-BOLTS.

Specification forming part of Letters Patent No. 190,555, dated May 8, 1877; application filed December 13, 1876.

To all whom it may concern:

Be it known that I, JOHN H. (JOMBS, of Stamford, Fairfield county, Connecticut, have invented an Improvement in King-Bolts for Carriages; and I do hereby declare the following to be a full and correctdescription of the same, reference being had to the accompanying drawings, in which Figure l is a front view; and Fig. 2 is a cross-section taken through a; m, Fig. 1. Fig. 3 is a transverse section taken on line y 3 Fig. 2; and Fig. 4 is a detail view, showing a modification.

My invention relates to that class of devices known as king-bolts, and used to secure the forward axle of a carriage or other land conveyance to the head-block or reach. It may also be used to secure the whiftletree to the pole, or may be used in any other suitable place about a carriage.

My invention consists in interlocking aclip 'having a centering-pin, and straddling the axle, with a clip fastened to the under side of the head-block, both of which clips bear upon a centeringplate upon the axle. This construction avoids the perforation of the headblock, spring, or axle; may be easily oiled, and is an additional security in case the centering-pin should break.

In the drawings, Arepresents the axle of a carriage, and B the head-block, with a portion of a spring shown upon its top.

0 and G are the fifth-wheel, part of which is secured to the axle and part to the headblock, in the usual manner.

D is the reach, passing through the head block. a is a clip, straddling the axle A, and secured by a plate and nuts underneath, in the usual manner. The clip a has a centering-pin, a, underneath its head, projecting downward.

Secured to the under side of the head-block B is the clip b, having a center orifice, 1), into which thecentering-pin a operates, the head of the clip a resting upon the top of the clip b.

Beneath the clip b, and resting upon the axle A, is a centering-plate, o, screwed or otherwise secured to the top of the axle, and embracing the legs of the clip a. Upon this plate is another centering-pin, c, projecting upward into the centering-pin b.

The plate 0, however, may have a hole, 0', through it, and the centering-pin b be solid and extend down into said hole 0, as shown in Fig. 4. This construction is sometimes preferable, and is fully embraced by my invention.

Through the head of the clip a, is an oil-hole, 0, into which oil may be poured into the joints below, completely oiling all the parts in contact without taking the bolt apart, which is an advantage over all other king-bolts in use.

Another advantage arising from my improvement is, that no holes are made in the axle, head-block, or spring, thus allowing them to retain their original strength and durability;

Still another advantage is, that if the centering-pin should break, the clips being interlocked, the axle and head-block would still be held together, and a serious accident may be avoided.

The same advantages and features are also applicable to whiffletree-bolts, or other parts of carriages.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A king-bolt for a land conveyance, in which the clip upon the axle is interlocked with the clip upon the head-block and combined with a centering-pin, substantially as described.

2. A king-bolt for a carriage, consisting of the parts a, b, and 0, combined and arranged substantially as described.

The above specification of said invention signed and witnessed, at Stamford, this 25th day of November, A. D. 1876.
